01General information

Description

HCC1569 是一种人类乳腺癌细胞系,来源于原发性导管癌。它具有基底样表型,雌激素受体(ER)阴性、HER2 阳性,是一种具有独特临床和治疗意义的分子亚型。与其他基底样乳腺癌一样,HCC1569缺乏ER和孕激素受体(PR)的表达,但它显示出ERBB2(HER2)癌基因的扩增和过表达,而ERBB2是HER2导向疗法的关键靶点。该细胞系表现出高度非整倍体,并存在与乳腺癌生物学相关的多种基因组改变。

HCC1569 被纳入大规模基因组剖析工作,如癌症细胞系百科全书(CCLE)和整合突变、拷贝数、甲基化和表达数据的相关研究。这些数据集显示,HCC1569 携带的结构变异和拷贝数扩增与侵袭性乳腺肿瘤(包括涉及 HER2 的肿瘤)一致。功能基因组筛选强调了该细胞系对 HER2 信号通路的依赖性,支持将其用于评估 HER2 靶向疗法和耐药机制。

此外,HCC1569 还具有 HLA 基因型和表达谱特征,这对免疫疗法的开发具有重要意义。它已被列入 HLA 分型和新抗原预测目录,为探索 HER2 阳性乳腺癌背景下的 T 细胞表位呈现和免疫识别提供了机会。这种免疫基因组注释使 HCC1569 不仅成为研究致癌信号转导的宝贵资源,也成为评估肿瘤与免疫相互作用和设计个性化免疫疗法的宝贵资源。

Thawing and culturing
  1. Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.

  2. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required.

  3. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains.

  4. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.

  5. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently.

  6. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

  7. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.

  8. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.

07Quality control and cryopreservation

Sterility

使用基于 PCR 的检测方法和基于发光的支原体检测方法排除支原体污染。

为确保没有细菌、真菌或酵母菌污染,每天都要对细胞培养物进行目视检查。

Freeze medium
我们使用完全生长培养基(包括 FBS)+10% DMSO 或 CM-1(Cytion 商品目录编号 800100)作为冷冻保存培养基,以获得足够的解冻后存活率,CM-1(Cytion 商品目录编号 800100)含有优化的渗透保护剂和代谢稳定剂,可提高恢复能力并减少冷冻引起的应激。
Storage conditions

如需长期保存,可将样品瓶放入气相液氮中,温度约为 -150 至 -196 ℃。在-80 °C下保存只能作为转入液氮前的短暂过渡。

Shipping conditions

冷冻保存的细胞系用干冰装运,并用经过验证的隔热包装和足够的制冷剂在整个运输过程中保持约 -78 °C 的温度。收到货后,应立即检查容器,并立即将小瓶转移到适当的储藏室。
